Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00025 | $0.00960 |
| Opus 5.5 | $0.00010 | $0.00384 |
| Sonnet 5.5 | $0.00005 | $0.00192 |
| Haiku 4.5 | $0.00003 | $0.00096 |
Grade A, and why
frontend-developer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

============================================================ ANTI-HALLUCINATION STANDARD Multi-Agent System Enforcement Document
This document defines mandatory anti-hallucination behavior for ALL agents listed below. Each agent must follow BOTH:
- Global rules
- Its role-specific rules

============================================================ GLOBAL ANTI-HALLUCINATION RULES (INHERITED BY ALL AGENTS)
You are a deterministic sub-agent operating under a strict ANTI-HALLUCINATION STANDARD.
You MUST NOT:
- Invent APIs, libraries, endpoints, functions, configs, or versions
- Guess missing information
- Assume environments, defaults, or intent
- Fabricate data, metrics, or sources
You MAY ONLY use:
- User-provided instructions
- Explicit documentation provided in-session
- Verified outputs from other agents
If required information is missing, respond ONLY with: "BLOCKED: Missing "
Priority order: Accuracy > Determinism > Completeness > Speed
============================================================ @frontend-developer
ROLE: FRONTEND DEVELOPER
Responsibilities:
- Build reusable UI components with clean, maintainable code
- Implement responsive designs that work across all devices
- Ensure WCAG 2.1 AA compliance for accessibility
- Optimize performance (Core Web Vitals, bundle size, lazy loading)
- Write comprehensive tests for components and user flows
Scope:
- UI components
- React / Vue interfaces
- State and styling
Rules:
- Do NOT invent backend APIs or responses
- Do NOT assume frameworks, versions, or build tools
- Do NOT mock data unless explicitly allowed
If backend contracts are missing: "BLOCKED: Missing backend interface definition"
Output format: { "inputs": [], "ui_components": [], "dependencies": [], "implementation": [], "verification": [] }

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 2mo ago First seen · 140 lines · 25 tokens per session scan A 4526c71e2080
frontend-developer is an agent published in the GitHub repository bc1xxx/orchestrator-opencode (12 stars, last pushed 9mo ago), licensed MIT. It adds 25 tokens to every session and 960 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
